90808-99-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90808-99-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,0 and 8 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 90808-99:
(7*9)+(6*0)+(5*8)+(4*0)+(3*8)+(2*9)+(1*9)=154
154 % 10 = 4
So 90808-99-4 is a valid CAS Registry Number.

Reactions of Organic Anions, 177. Vicarious Nucleophilic Substitution of Hydrogen, Bisannulation and Competitive Reactions of α-Haloalkyl Carbanions with Bicyclic Azaaromatic Compounds

Makosza, Mieczyslaw,Golinski, Jerzy,Ostrowski, Stanislaw,Rykowski, Andrzej,Sahasrabudhe, Arvind B.

, p. 577 - 585 (2007/10/02)

Carbanions of α-haloalkyl aryl sulfones, sulfonates, and sulfonamides react with bicyclic heteroaromatic compounds (quinoxalines, naphthyridines, and 5-azaquinoxalines) according to two general pathways: vicarious nucleophilic substitution of hydrogen and/or bisannulation.In some cases other competitive reactions such as SNAr are observed.Factors governing the direction of these reactions are discussed in terms of the charge distribution in the anionic ? adducts and the reaction conditions.
